Okay, my pH is only slightly high, 7.4-7.5. I would like it to be at 7, maybe a little bit higher. I keep on hearing about using peat in the filter to soften water. Where do you get peat? How much do you use? Do you leave it in all the time, or only for a while? Is it applicable in my situation? Should I use one of those proper ph powders instead? How many questions can fit in one post???????
